ATTORNEY Patented Apr. 23, 1935 UNITED STATES PATENT oFFmE.

Application August 17, 1929, Serial No. 386,661 Renewed August 8, 1933 14 Claims.

This invention refers to window locks and more particularly to that class for application to sliding windows moved in planes relatively one to the other.

It'is often found advisable to open a sliding window of the rise and fall type more generally employed in building construction. Permanent openin s of such windows are more generally for the purpose of ventilation and may be sufiiciently small to prevent an unauthorized person to enter theretlirough. Whereas locking arrangements have. been heretofore attached to such windows, with any appreciable opening, it is quite possible for an unauthorized person to insert simple tools and no-iselessly release the locking arrangement whereby the window may be more widely opened for unauthorized entry by said unauthorized persons therethrough. ,It is therefore one object of this invention to furnish window locking means whereby windows may be opened within certain limits by authorized or unauthorized persons, the opening being sufficiently small to prevent unauthorized persons passing therethrough, the lockin means being so arranged whereby only authorized persons may effect a larger opening of said windows.

Furthermore many large and tall hotels and apartment houses are being erected, the living quarters of which are at considerable heights 39 above the ground, or street level. The number of persons who becomedizzy when looking down from great heights is, surprisingly large and as a result many accidents and even deaths have been recorded, due to persons either jumping. or falling from windows situated at considerable height above the ground. It is, therefore another object 01' this invention to provide locking means for Windows whereby tenants. of hotels or apartments may open their windows sufiiciently for ventila- 49 tion, but. cannot open said windows sufficiently to have egress therethrough. v

l flther object is to furnish a novel locking apparatus for rise and fall Windows whereby the windows may be key locked to permit a comparatively small but variable opening for ventilation pair-posesv but will prevent sufficient openingthereof whereby human beings may pass therethrough. Another object is to furnish a novel key locking appa atus which maybe applied to windows in a so simpler manner than is customary and which will have a pleasing finished appearance. v 7

Another object is to furnish an ovel locking arrargement for windows whereby in opening the window the shock, caused by the. unexpected stop- Ring ofthey window. at. the comparatively short distance set by the look when the intention was to raise the window to a greater distance willbe resiliently absorbed.

Another object is to furnish anovel locking arrangement for windows whereby no movable 5 mechanism is seen from the interior ofthe room.

Another object is to furnish a novel locking arrangement for windows wherein standard key cylinder lock units may be employed so that the window'locks may be master keyed. 10

Another object is to furnish a novel lockin arrangement for windows whereby the lower window may be raised, or the upper window may be lowered within certain limits and further opening thereof can only be eflected by key operation 15 by authorized persons.

Other objects and advantages will appear as the description of the invention progresses and the novel features will be pointed out in the appended claims.

In describing the invention in detail, reference is had to. the accompanying drawing wherein like characters of reference designate like parts throughout the several views and in which:-

Figure 1 is an enlarged partly sectional View 25 of a preferred form of applicants invention taken on line l-l of Fig. 2, and Fig. 2 is an elevational view of the same taken on line 2--2 of Fig. 1, and Fig. 3 is a plan View of a window sash and windows therein fitted with applicants novel locking 30 apparatus, and Fig. 4 is a perspective view of a preferred form of shock absorber.

, Referring to Figs. 1, 2, 3, and 4, the lock unit 1 comprises cylinder plate 2 having extensions 3- -3 arranged to receive wood screws as d-d or a machine screw. as 56 for securing said plate to side member 5 of window frame 5, also orifice 1 arranged to receive cylinder lock unit 8 of known form having cylinder 9 arranged to be rotated by insertion of key l0 into slot H therein. To ll) the inner end of cylinder 9 is secured disk member l2 having slot l3 arranged to receive one end of fiat sided screw member l4, pin 15 acting to loosely allocate said screw member end in said slot, said disk member also serving to prevent re,- moval of said cylinder and being secured thereto by screw l6.

Cylinder plate 2- is also formed with annular flange ll arranged to receive cylinder portion l8 of barrel member 19' having extensions. 20-20 similar to extensions 3-3 also securedto side member 5 by screws as 4, or machine screw as 5.6, said side member 5 being drilled to form the cylindrical orifice 2! arranged 'to receive the 5 til shoulder 22 of said barrel member and flange i! of cylinder plate 2.

Barrel member I9 is formed with a cylindrical bore 24 arranged to receive piston member 25, and a counter-bore 26 arranged to receive bolt plate 27. Said barrel member is also formed with slot 35 arranged to receive pin 35 secured in said bolt plate 2'! whereby said plate is allocated in said barrel member, said slot also serving to drain any moisture which may accumulate within the locking unit I.

Piston member is formed with cylindrical portion 28 arranged to reciprocate in core 24 of barrel member 19, also with a head portion 29 having a bolt portion 30 and also with acylindrical portion 3! formed integrally with the head and cylindrical portions, said cylindrical portion being substantially co-axial with the cylinder 9 and formed with an internally threaded orifice 32 arranged to receive the threaded screw M, a disk 33 secured in counter-bore 34 serving to seal said orifice. Said head and cylindrical portions are joined by re-enforcing ribs 3?.

Referring to Figs. 3 and 4, to the under side of the bottom member of upper window 4! is seciued the shock absorber 42 comprising buffer 43 arranged to be clampably allocated by bracket 44 secured to said window by screws 45--45.

Referring to Figs. 1 and 2, the bolt plate 27 is formed with an orifice 5!] arranged to receive bolt portion 38, cylindrical portion 3! and the re-enforcing ribs 5l5l therebetween. Said plate is also formed with orifices 5252 arranged to receive screws 5353, the threaded portion 54 of which is arranged to enter threaded bosses 55-45, said screws acting to allocate said bolt plate 2'1 in counter-bore 25 and cylinder unit 8 in orifice i. The heads 5151 of screws 53-53 are preferably sealed by the application of seals as more fully disclosed by applicants co-pending application, Serial No. 180,7 98, filed April 4, 1927, whereby they cannot be removed by unauthorized persons.

Through bolts or machine screws as 55 may be employed at both the upper and lower extensions as 33 whereby the cylinder plate 2 and barrel member are clampably allocated to re-enforce the side member 5 and thereby compensate for any weakening thereof due to the forming of the orifice 2!, the extensions 2fl20 being suitably threaded to receive the threaded ends 58 of screw 56.

Bolt plate 21 may be permanently secured in counter-bore 26 by soldering, swedging or pinning, as may be preferred and whereby it cannot be removed.

Cylindrical portion 28 of piston 25 is preferably relieved by annular recess 59 to reduce weight and machining thereof.

Operation The parts of lock unit I are normally positioned as shown, the screw I 4 partially entering the threaded orifice 32, as shown, cylinder 9 being locked by the key operated pins in cylinder unit 8 in known manner. In Figs. 1 and 2, it is assumed the window 6 has been raised until the bolt face 45 has engaged the face 41 of buffer 43, the distance of opening being represented by the distance X, assumed to be approximately eight inches, or less depending upon the landlords choice of location of the lock unit I on the side member 5.

Assume it is desired to open the windows 5 and 4| the entire distance of opening-for the purpose of window washing. An authorized person will insert the key I0 into slot 1! of cylinder 9 rotating said cylinder clock-wise thereby causing the threads of orifice 32 to be drawn onto the screw I 4 by the rotation of said screw, in this manner moving piston 25 to the left within cylinder bore 24, said movement also causing bolt portion 35 to move to the left until its face 48 is substantially parallel with face is of bolt plate 21 and whereby the surface is out of register with surface 41 of buffer 43, thus permitting the free movement of windows 6 and ii without restraint by locking unit I.

The lead of the threads of screw !4 and orifice 32 is preferably formed whereby the bolt 30 is withdrawn upon the cylinder being rotated approximately 300 degrees in this manner making it impossible to remove the key without again moving the piston 25 to the right whereby said bolt will intercept the buffer 43. Screw I4 is preferably drilled to receive a pin as 59 arranged to impinge on face 69 of cylindrical portion 32, said pin acting as the stop for the inward movement of said piston by the impingement of said pin against said face 60.
